Mechanisms Underlying the Protective Vascular Effects of Dietary Potassium in Humans

Recruiting now · Not applicable

Conditions studied: Cardiovascular Risk Factor

In brief

Americans continue to consume high amounts of sodium. Potassium is notable for its blood pressure lowering effects but less is known regarding its effect on the vasculature. This investigation seeks to determine the role of dietary potassium on the vasculature in the presence of a high sodium diet in salt-resistant adults.
